Arnaud Cassan Optical and Infrared Wide-Field Astronomy in Antarctica ARI / ZAH Heidelberg IAP, 14 – 16 June 2006 Why Dome C ? With he current setup : –Gaps in the light curve –Multi-site photometry = difficulties with combining data sets from different telescopes (mean seeing/air mass, weather conditions, CCDs…) –Australia do not provide stable weather conditions to operate a deep round-the-clock monitoring  Only 1 terrestrial planet so far Given that : - the theoretical efficiency is higher than is achievable now - the main difficulties come from -the non-continuous monitorin -The weather conditions - the statistical point of view is the most relevant for microlensing search for exoplanets ► The ground base detection capabilities have been reached ► Dome C is the most relevant site to achieve the ultimate goal of microlensing searches for exoplanets = statistical aspect
